Effectively those who fly on instruments/autopilot will prefer to fly high, and that will bring in a degree of separation. My issue is with those pilots who plan to fly lower and mix it with us 'indians' then blame us for getting in their way - quoting safety as a rationale.
Sometimes it's not possible to fly higher, either to avoid icing, or regulated airspace above.
I don't think anyone is blaming "us indians"- who is that group, anyway? As far as avoidance and "getting in the way" is concerned, the rules of the air apply to everyone, irrespective of nationality.
